LANCASTER prefixes in area code 717
NANPA records 101 assigned NXX blocks to rate center LANCASTER in area code 717, 12.9% of the 784 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 15 holders hold those blocks, the largest being VERIZON PENNSYLVANIA, INC. (24), NEW CINGULAR WIRELESS PCS, LLC - DC (22), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - PA (15). The earliest assignment on record here is 2001-06-18 and the most recent 2017-01-04. 65 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 218, 220, 223, 603 – overlay codes cover the same geography, so a rate center is served by all of them.
